there are several companies performing R&D as we speak. there is one company that said the cams were available, but i wouldnt buy a single thing from that company. they had a thread on another forum and shot themselves in the foot with their comments. several people said they saw stuff at sema also.
Yes, BBR IS a real company. No, I would not buy anything from them. Check out any of the bigger forums and you will see pissing contests all about thier claims.
Comp, Crower, and (I think) Crane all had cams at SEMA, but none of them have put them into production as far as I know. AFM has sets that they are selling, but I haven't seen any numbers yet.
